LGY1E123MELA40

The LGY1E123MELA40 is a snap‑in terminal aluminum electrolytic capacitor designed for high‑reliability, long‑life power applications. As a member of the LGY series, it provides high bulk capacitance in a radial, can snap‑in package intended for industrial power supplies and ballast circuits.

Key benefits include a 25 V rated voltage, 12,000 µF capacitance, wide operating temperature range from –40°C to +105°C, and long life assurance with 5,000 hours of rated endurance at 105°C. The part is RoHS compliant and polarized for DC applications.

Key Features

• High Capacitance: 12,000 µF (12 mF) bulk capacitance for energy storage and smoothing in power circuits.
• Rated Voltage: 25 V nominal rated voltage suitable for many DC power rails.
• Temperature & Longevity: Operational range –40°C to +105°C with endurance specified as 5,000 hours at 105°C.
• Package & Mounting: Radial, can snap‑in package with snap‑in terminals for secure PCB mounting and robust mechanical retention.
• Ripple Current Capability: Rated ripple current of 2.6 A at 120 Hz and 2.99 A at 50 kHz for handling AC ripple on DC rails (series frequency coefficients apply).
• Electrical Characteristics: Capacitance tolerance ±20%; leakage current defined by I ≤ 3√(C·V) μA after 5 minutes at 20°C; tan δ (25 V) max 0.40 per series specification.
• Compliance: RoHS compliant as specified for the LGY series.

Typical Applications

• Industrial Power Supplies: Bulk filtering and energy storage where long life at elevated temperature is required.
• Ballast Circuits: Suitable for ballast applications as indicated for the LGY series, providing stable capacitance under ripple stress.
• General Purpose DC Filtering: High capacitance and ripple handling for smoothing and decoupling in medium‑power DC systems.

Unique Advantages

• Long Life Assurance: 5,000‑hour rated endurance at 105°C delivers predictable performance over extended operating periods.
• High Bulk Energy Density: 12,000 µF in a 40 × 25 mm footprint (L: 4 × D: 2.5 cm) reduces the number of discrete capacitors required for bulk storage.
• Robust Ripple Handling: Specified ripple current at both 120 Hz and 50 kHz helps manage heating and lifetime in applications with significant AC components.
• Wide Temperature Range: –40°C to +105°C rating supports demanding operating environments without sacrificing capacitance stability.
• Measured Electrical Limits: Clear leakage current and tan δ limits (I ≤ 3√CV μA; tan δ max 0.40 at 25 V) provide predictable design margins for reliability and performance.
• RoHS Compliant: Meets RoHS directive requirements for regulatory and environmental alignment.
